You can do your own compare to see what they’re offering, but it’s pretty clear that Joyent is damned proud of their Solaris+ZFS setup, as they seem to have the least amount of disk and transfer available. Rackforce talks about the virtual to physical ratio, but 1and1 doesn’t say a thing.

As far as I can see, any small company hosting their own hardware is probably going to need a darned good business reason. The cost of hosting your own setup is really getting a competitor.
